1 / 12 page  RT9705B 1 DS9705B-03 April 2011 www.richtek.com 80m Ω Ω Ω Ω Ω, 1A Power Multiplexer General Description The RT9705B is a dual input single output power multiplexer specifically designed to provide seamless voltage transition between two independent power suppliers. Equipped with two low RDS(ON) N-Channel MOSFETs driven by internal charge pump circuitry, the RT9705B is able to deliver 1A output current with only 80mV voltage drop. Manual or auto switching mode is easily selected by two digital inputs D1 and D0. When both D0 and D1 are selected high, the RT9705B enters shutdown mode and consumes minimum power making it ideal suitable for battery powered equipments. A STAT pin with open drain output is provided to indicate the switch status. A user-programmable up to 1.25A current limit function is available for maximum safety in various applications. The RT9705B provides comprehensive protection functions, including adjustable current limit, over temperature protection, soft start function for minimum inrush current, cross-conduction protection, and reverse conduction protection. These features greatly simplify power multiplexer design. The RT9705B is available in TSSOP-8 package requiring minimum board area and smallest components. Features Adjustable Current Limiting up to 1.25A Built-In (Typically 80m Ω Ω Ω Ω Ω) N-Channel MOSFET Reverse Current Flow Blocking (no body diode) i.e. Output Can Be Forced Higher than Input (Off-State) Low Supply Current : 55 μμμμμA Typical at Switch on State Less than 0.5 μμμμμA Typical at Switch Off State Guaranteed 1A Continuous Load Current Wide Input Voltage Ranges : 2.8V to 5.5V Open-Drain STAT Output Hot Plug-In Application (Soft-Start) Thermal Shutdown Protection Smallest TSSOP-8 Package Minimizes Board Space RoHS Compliant and 100% Lead (Pb)-Free Applications LCD Monitor, LCD-TV Information Appliance and Set-Top Box Battery-Powered Equipment ACPI Power Distribution Motherboard & Notebook PCs Mini PCI & PCI-Express Cards PCMCIA & New Cards Pin Configurations (TOP VIEW) TSSOP-8 Ordering Information STAT D0 D1 ILIM GND VIN2 VOUT VIN1 4 2 3 5 7 6 8 Note : Richtek products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes. Marking Information For marking information, contact our sales representative directly or through a Richtek distributor located in your area.
